Yet another idea on modeling DRAM power usage

[rootfs]

Would DAMON tracepoints be useful in modeling DRAM power? It has memory access pattern stats in it so maybe we can use it for power modeling.

@rootfs this is interesting.

Currently, we are measuring the virtual page cache access.
With a quick view, it seems that DAMON is also doing that.

But it might be worth checking if the metric is different.
